A major part of the waterproof cooling fan

"Waterproof Cooling Fan" The main components are: AC motor. Its working principle is: energized coil in a magnetic field by the force of the rotation. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into heat. When the fan work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise. Let us analyze a cause of temperature rise: When fans work, due to current through fan coil, "Waterproof Cooling Fan" wire is resistance, it will inevitably produce an exothermic heat outside, so the temperature will rise. But why people will feel cool it? Because the body's surface have a lot of sweat, When fans work together, indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with "evaporative need to absorb a lot of heat" so people will feel cool. Parallel Fans: dual fans constant pressure in parallel, but will increase the amount of wind. "Waterproof Cooling Fan" to increase air flow and therefore increase the cooling effect, in the design of power if the heat is too small, you can consider increasing the fan to resolve. Series Fan: Results of the series fan is pressure to increase, but the wind changed. This approach is not to solve the heat problem, generally used in the past when much wind resistance adopted to ensure that the amount of wind.
